BARREL-TAPPING DEVICE.

Specification of Letters Patent.

Patented Feb. 29, 1916.

Application filed December 5, 1912, Serial No. 735,150. Renewed April 24, 1915. Serial No. 23,765.

.Columbia, have invented certain new and useful Improvements in Barrel- Tapping Devices, of which the following is a specification.

The present invention relates to certain new and useful improvements in barrel tapping devices, and has for its primary object to provide a device of this character which is simple and inexpensive in its construction, and which embodies certain novel features whereby the valve is always tightly seated when the coupling member is withdrawn.

A further object of the invention is to provide a barrel tap which can be readily placed in position or removed therefrom, thereby admitting of the tap member being removed from the barrel when burning or repitching the same. This is a very advantageous feature of construction, since it prevents the pitch from entering the tap member so as to clog the same and interfere with the free operation of the valve, and also in the fact that it eliminates all danger of injuring or destroying the stave or side of the barrel or container in which the tap 1s mounted.

A still further object of the invention is to provide a barrel tapping device in which the valve member is mounted in a novel manner so that it can be easily and quickly moved into an open or a closed position, yielding means being provided which is automatically placed under tension when the valve is closed and serves to hold the valve firmly upon its seat.

With these and other objects in view, the invention consists in certain novel combinations and arrangements of the parts as will more fully appear as the description proceeds, the novel features thereof being pointed out in the appended claims.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings, in which Figure 1 is a longitudinal sectional view through a barrel tap constructed in accordance with the invention, the valve being shown in a closed position, and portions being broken away and shown in section to more clearlyillustrate the invention-.- Fig...

2 is an enlarged transverse sectional view through the thimble of the tap member, looking toward the inner end thereof. Fig. 3 is an enlarged longitudinal sectional view through the inner end of the thimble or tap member, the valve being shown in an open position. Fig. 4 is a detail perspective view of the spring. Fig. 5 is a similar view of the valve seat, and Fig. 6 is a similar View of the valve member.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Specifically describing the present embodiment of the invention, the numeral 1 designates the bushing which is adapted to be permanently fitted to the barrel or other container. The exterior of the bushing is provided with the coarse wood threads 2 which are adapted to engage the walls of the usual opening to hold the bushing firmly in position. The interior of the bushing is provided with the left hand threads 3, while the outer end of the bushing is notched at 4 so as to be readily engaged by a spanner or wrench when screwing the same into or out of position.

A sleeve 5 is fitted within the bushing 1, the exterior of the sleeve being provided with the left hand threads 6 which are adapted to engage the interior left hand threads 3 of the bushing. This sleeve or thimble 5 carries the entire valve mechanism and is removably fitted within the bushing 1 so as to be readily unscrewed therefrom for the purpose of making repairs, or when it is desired to burn or repitch the barrel. Owing to the fact that the exterior threads 2 of the bushing are ordinary right hand threads while the interior threads 3 of the bushing are left hand threads, it will be obvious that there will be no danger of unscrewing the bushing from the barrel when attempting to remove the thimble or tap member from the bushing, since the clockwise rctation of the thimble necessary to remove the same will only tend to seat the bushing more firmly in position.

The inner end of the thimble 5 is rabbeted at 7 to provide a seat within which a ring 8 is mounted, the outer edge of the ring being provided with a beveled seat 9. A spider 10 is mounted within the outer end of the ring 8,-the said spider being formed with the four radial arms 10 which have the extremities thereof rigidly connected in some suitable manner to the ring. The central portion of the spider is provided wlth an v opening through which the valve stem 11 eX- valve is moved into a closed position. The

central opening of the spider 10 is surrounded by a flange 13 having a pair of oppositely disposed cam notches let therein. It will also be observed that the inner face of the valve 12 is provided with the projections or cam members 15 which correspond. to the notches 14 and are received within the said notches when the valve is in a closed position. However, when the valve is rotated so as to cause the ribs or projections 15 to ride out of the cam notches 11, as indicated by Fig. 3, the valve 12 is moved away from the valve seat so as to open the valve.

- A collar 16 surrounds the valve stem 11, the said collar being provided with the spring arms 17 which correspond'to the four arms 10 of the spider 10 and engage the same. In order to hold the collar 16 and spring arms 17 against rotation with the valve stem, a pair of the arms 10 of the spider are provided with upturned portions constituting guide wings or lugs 18 between which the corresponding spring arms 17 are re ceived. The collar 16 is provided with a pair of oppositely disposed cam shoulders 19 which are adapted to be engaged by lateral projections 20 upon the valve stem 11. In the present instance these lateral projections 20 are formed by the projecting ends of a transverse pin which is passed through the valve stem. The cam shoulders 19 of the collar 16 correspond to the cam notches 14 of the flange 13 upon the spider 10, although they are disposed in an opposite manner. WVhen the valve 12 is in a closed position, as indicated by Fig. 1, the projections 15 of the valve member are received within the notches 14 of the flange 13, and the projections 20 of the valve stem are in engagement with the cam shoulders 19 of the collar 16 so as to force the said collar inwardly toward the spider and produce tension in the spring arms 17 the said tension in the spring arms 17, serving to hold the valve member yieldingly in position upon the valve seat. When the valve 12 is rotated to open the same, as shown by Fig. 3, the projections 15 of the valve member are rotated out of engagement with the cam notches 14 of the flange 13 so as to move the valve member away from the valve seat, and the projections 20 of the valve stem are simultaneously moved out of engagement with the cam shoulders 19 of the collar 16 so as to release the tension in the spring arms 17. It will thus be obvious that when the valve is again rotated to close the same, the projections 20 of the valve stem are again brought into engagement with the cam shoulders 19 of the collar 16 so as to move the said collar inwardly toward the spider and produce tension in the spring arms 17 for holding the valve member firmly upon its seat. The inner end of the valve stem 11 has the usual polygonal or angular formation as indicated at 21 so as to be readily engaged by the usual type of coupling member, the said cou pling member being adapted to interlock with the sleeve by means of the conventional bayonet slot joint. When the coupling member is applied to the sleeve and rotated to produce an interlocking connection therewith, the valve 12 is opened, as previously explained, while when the coupling member is rotated to break the interlocking connection with the thimble, the valve member is closed. The coupling member can not possibly be removed. without rotating'the valve member a suflicient amount to bring the cam projections 15 into a partial engagement with the notches l4: and bring the projections 20 into engagement with the cam shoulders 19 of the collar 16 so as to produce tension in the spring arms 17. This tension in the spring arm 17 would be suflicient to complete the closing of the valve and to hold the valve firmly upon its seat. A tight seating of the valve is always assured, thereby eliminating any possibility of leakage of the liquid or escape of the gases with which the liouid is charged. 7
